The various kinds of data are stored in the allocated CIO Area words, which
are identified by the offset from the beginning word (n) allocated to each Unit.
There are two patterns for the layout of the allocated CIO Area words: the
default settings and user settings. The layout can be selected in the Status
Area settings in the Edit Parameters Dialog Box from the CX-Programmer.
To set a customer areas, select User defined for the Layout Type on the Sta-
tus Area Tab Page.
The beginning word n is calculated by the following equation:
Bit
15
Beginning word n = CIO 1500 + (25 × unit number)
Note The reserved words are regularly refreshed with all zeroes.
